RAG-CUTTING. MACHINE.

SPECIFICATION forming part of Letters Patent No. 453,380, dated June 2,1891.

Application filed September 15, 1890. Serial No. 365,060. (No model.)

To all whom it may concern.-

Be it known that I, J AMES W.T1NoHER, of Xenia, Clay county, Illinois,"have invented certain new and useful Improvements in Rag and LeatherCutting Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompany" ing drawings, forminga part hereof.

My invention relates to improvements in machines for cutting'rags orother analogous material; and it'consists in the novel arrangement andcombination of parts, as will be more fully hereinafter described, anddesig nate'd in the claims.

The object of my invention is to construct a machine to be used in theshoddy business to out rags which are to be run through a machine thattears them all up, and said strips are then run through woolen cardsmade for the purpose. The material is then like the original wool, onlyshorter in fiber.

In the drawings which serve to illustrate my invention, Figure 1 is afront elevation of. my complete invention. Fig. 2 is a verticallongitudinal section of the same. Fig. 3 is a horizontal section of thetension device, taken on the like a m, Fig. 4. Fig. 4 is a verticalsection of the same, taken on the line y y in Fig. 3. Fig. 5 is atop-plan view of the connecting-link. Fig. 6 is a vertical cross-sectiontaken on the line 2 z of Fig. 2. Fig. 7 is a side elevation of one ofthe disks or feed-rollers and rotary cutter detached. Fig. Sis a frontelevation of one of the disks or feedrollers, and Fig. 9 is a frontelevation of one of the rotary cutters.

Referring to the drawings, 1 represents the table of my improvedrag-cutter, which is ion is mounted on a stud 48, and which stud issecured in an arm 10, secured to table 1. Located in arm 10 is ahorizontal shaft 11, which carries at each end thereof toothed wheels 12and 13. Toothe'd wheel 12 of said shaft is adapted to engage inpinion-wheel 9, v

and toothed wheel 13 is adapted to engage in a toothed wheel 14, whichwheel 14 is mounted on a short horizontal shaft 15. Said shaft 15 issuspended from arm 10,'and is mounted on bearings 16 and a U-shapedrecess formed in said arm. Said shaft 15 also carries at its outer end arotary cutter '18, which overlaps cutter 5, mounted on shaft 1.

The cutters 5 and 18 overlap each other in a transverse slot 19, made inthe plate 1, thereby forming a pair of rotary shears. Said rotarycutters are secured between two pairs of circular disks 20 and 21,respectively, and said pairs of disks are mounted on shafts 4t and 15,respectively, by means'of nuts 22 and 23. The outer disk of cutter 18 isprovided with a rabbet 24, formed around its periphery, to permit theoverlapping portion of cutter 5. to move freely therein in its revolvingmotion. Likewise the inner disk of cutter 5 is provided wit-h a similarrabbet formed around its periphery to permit cutter 18 to move therein.Said disks 21 are situated diametrically above disks 20, andthe plane ofthe circumferences of disks 21 comes in contact with the plane of thecircumferences of disks 20 at a point above the surface of table 1. Theintensity of contact between said disks is regulated by an adjustable'frame-tension device 25, which is located in arm 10. Theinnerend of said frame is provided with a bearing 26 for shaft 15 to rotatein, and the outer end is provided with a U-shaped, recess which fitsover shaft 15. The four uprightpieces of said frame pass throughperforations made in the upper web of the arm 10 and connected at theirtops by cross-pieces 27 and 28 The lower ends of said upright pieces aresecured in plates 28 and 29. Plate 28 forms a bearing for shaft 15, andplate 29 has a U-shaped recess, which fits over shaft 15. Said platespass through perforations made in the lower web of the arm 10. Saidupright pieces are connected longitudinally by plates 30, which platesare composed of two pieces, and each piece is provided at its oppositeends with U-shaped recesses, and when said pieces are placed upon eachother with therecesses facing each other they form a circularperforation, which fits over the upright pieces. Said pieces are clampedover said upright pieces and upon each other by Ineansof screws 31. Onthe cross-pieces which transversely connect the upright pieces asemi-elliptic spring 32, with one end bent upon itself and sprungoutwardly from the body of the spring, is placed. One end of said springbears on cross-piece 27 and the other or bentportion on cross-piece 28*,and is held in said position by means of a thumb-screw 33, which passesthrough a perforation 34 in said spring and screws in the arm 10. hensaid screw 33 is screwed down, it presses 011 the spring, and saidspring transmits its pressure to the frame 25, and said frame bearsdirectly on the shaft 15, which carries disks 21, and thereby forms ayielding pressure between said disks 21 and 20. This yielding pressureis absolutely necessaryin cut-ting rags of unequal thicknesses, as theelasticity of the spring will allow different thicknesses to passbetween the disks without changing the adjustment.

The lateral adjustment between the rotary cutters is regulated by meansof a device 35, attached to the shaft 15 and fulcrumed on the arm 10 bymeans of a set-screw 36. Said device consists of a vertical lever 37,the upper arm of which lever is provided with a curved portion 38, whichfits freely over shaft 11. Said lever passes through rectangular slots50 and 51, formed, respectively, in the upper and lower web of arm 10and terminates at its lower extremity in a U-shaped recess 53, whichfits in an annular groove 54, made in shaft 15. The upper end of said1ever terminates in a rounded point, one corner thereof being cutaway,and is provided with a small triangular recess 40, adapted to fit in acorresponding protuberance 55, formed in the inner surface of aconnecting-link 41. Said connecting-link passes over a permanent plug42, formed on or secured to said arm 10. Said plug 42 is provided withan indentation 56, which passes about half through its thickness, and isprovided with screw-threads, which are adapted to receive a set-screw43, which passes through the end of said connecting-link. Saidconnecting-link is also provided at one end with screw threads adaptedto receive set-screw 43. The screw passes through said connecting-linkand screws in plug 42, and when the screw is tightened theconnecting-link is drawn toward the plug, and consequently the upper endof the lever drawn thereto, (for the connectinglink passes over theupper end of said lever,) and the lever,pressinginanopposite direction,presses against the face of groove 54, formed in shaft 15, and pushessaid shaft forward, and consequently the rotary cutter 18 against cutter5. This adjustment is very desirable, for in cutting thin cloth thecutters should be closer together than in cutting heavy and coarsematerial.

46 represents sheet-iron guards or casings, one of which is secured tothe arm 10 and the other to table 1. The object of these casings is toprevent cutting the limbs on the rotary cutters 5 and 1S.

47 represents a gage to regulate the size of the strips to be out.

\Vhen' it is desired to use or operate the machine by means of atreadle, I secure in the frame 2 a horizontal shaft 59, which said shaftis provided with a crank 60, and has also mounted on it a fly-wheel 61and a belt-pulle 1 62.

63 represents a short belt which passes over belt-pulley 62 andbelt-pulley 64, which pulley 64 is mounted on shaft'4, and by means of apitman 65, secured to crank and to a treadle 66, said shaft 59 isrevolved. When -it is desired to revolve the shaft 4 by means ofsteam-power, a belt is passed over belt-pulley 6, and the motor-wheel ofthe engine by which it is desired to operate said cutter. Vhen thecutter is operated by steam-power, the belt 63 is removed frombelt-pulley 62.

Toenable others to use my invention, I will proceed to describe itsapplication.

The article to be cut is inserted between the rotary cutters 5 and 18,and the disks 20 and 21, acting as feeders, will force the articleforward and keep it continuously in contact with the cutters. Thecutters being arranged between the disks or feeders, the material onboth sides of said cutters is held at the same tension, thereby makingit cut more easily and smoothly.

Having fully described my invention, what I claim is- 1. In a rag-cutterhaving two rotary cutters, one of which is situated diametrically abovethe other, with its edge overlapping the edge of the other, thecombination of four disks, one of which is located on each side of eachcutter, a tension device 25, by which the vertical pressure between saiddisks is regulated, a shaft 15, a vertical lever 37, connected to saidshaft so as to permit revolution of same, a projecting plug 42, a link41, which connects plug and lever, a set-screw 43, which passes throughone end of connectingliuk and into the plug, whereby the lateralpressure between the rotary cutters is regulated, and drivingconnections or gearing, substantially as set forth.
